Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data measuring instrument having a date and time management function for measuring data that fluctuates depending on the date and time of measurement, for example, data relating to a sample in a clinical test.

[0002]

2. Description of the Related Art Conventionally, there has been known a data measuring device for measuring data such as blood glucose level of a sample such as blood or urine in a clinical test. Some measuring instruments of this type are used by the sample provider itself, and are easy to handle even by inexperienced measuring personnel.
It is considered to be portable and small.

[0003] Such a small-sized data analyzer for clinical test incorporates a measurement circuit controlled by a microcomputer for measuring the concentration of components of a specimen and the like, and a display panel such as an LCD. In, when data is measured by a measuring circuit using driving power of a battery or the like, the measured data at the time of the measurement is displayed on a display panel.

[0004] Incidentally, it is known that data relating to a sample such as a blood glucose level, which is used as measurement data, slightly fluctuates even during one day. For this reason, some data measuring instruments for clinical tests have a function of storing and managing measurement data obtained from a measurement circuit in a memory together with measurement time obtained by a built-in clock.
In a data measuring instrument having such a date and time management function, data obtained together with the measurement time is temporarily stored in a memory,
After that, the data is displayed on the display panel together with the measurement date and time in response to the user's button operation. As a built-in clock for obtaining such a measurement time, a clock that counts the time based only on a clock signal generated by itself is generally used.

[0005]

However, in the conventional data measuring device having the date and time management function, only the internal clock counts the time while generating the clock signal by itself, so that an error occurs in the process of generating the clock signal. This inevitably occurs, and a mechanism for manually correcting the time is required as in a general wristwatch or table clock. In other words, a data measuring instrument that should be easy and small to handle for the measurer is always provided with a time adjustment button for time correction, in addition to a measurement button used when measuring original data. . For this reason, the data measuring instrument requires a troublesome operation of having to adjust the time each time using the time adjustment button when the battery runs out, and the time adjustment button that is not related to the original function is measured. There was a risk of being mistakenly operated at the time.

[0006] The present invention has been devised in view of the above circumstances, and can obtain measurement data together with the measurement time, and further requires any troublesome operation for time adjustment. It is an object of the present invention to provide a data measuring instrument that can easily and easily perform a handling operation without using it.

[0007]

The data measuring device 1 has a built-in battery serving as a drive power supply for the internal circuit. However, since this battery is the same as a conventionally known battery, detailed description thereof is omitted.

The receiving section 17 implements a receiving means for receiving a signal wave containing time information.

The clock section 18 realizes clock means for counting while correcting the time based on the signal wave received by the receiving means.

And a measurement management control means for storing the measurement data in the storage means together with the measurement data obtained by the method.

The display unit 19 realizes display means for displaying measurement management data, and the operation unit 20 includes operation means for performing a predetermined operation when displaying measurement management data. Has been realized, and CPU1
Reference numeral 1 denotes a display control unit that calls up the measurement management data stored in the storage unit from the storage unit and displays the measurement management data on the display unit according to a predetermined operation via the operation unit.

Next, the essential points of the operation of the data measuring device 1 having the above configuration will be described with reference to the flowchart shown in FIG.

FIG. 3 is a flowchart showing an operation procedure in the measurement process of the data measuring device 1. As shown in FIG. 3, first, the CPU 11
It is determined based on the detection signal whether or not it has been inserted into d (S1).

When the attached piece 2 is inserted into the insertion section 1d (S1: YES), the CPU 11 starts the operation of the receiving section 17 and the display section 19 (S2). As a result, the receiving unit 17 can receive a signal wave from a GPS satellite, while the display unit 19 displays a predetermined message or the like on the LCD display panel 1b by driving the liquid crystal.

When the reception unit 17 is enabled to receive the signal radio wave, the CPU 11 determines whether the reception unit 17 normally receives the signal radio wave (S3).

When the signal radio wave is normally received by the receiving section 17 (S3: YES), the CPU 11 acquires time data containing accurate time information from the received signal radio wave, and acquires the acquired time data. Based on the data, the clock unit 18 causes the clock unit 18 to correct the date and time and correct the date and time (S4). Accordingly, even if there is an error in the date and time measured by the clock unit 18 before the start of the measurement process, the date and time in the clock unit 18 are automatically adjusted at the measurement time point so that the time is accurately adjusted. Time.

After the date and time in the clock section 18 are corrected in this way, the CPU 11 obtains measurement data from the measurement section 16 which is conductively connected to the attached piece 2 (S5).

When the measurement data is obtained, the CPU 11
At the time when the measurement data is obtained, the date and time measured by the clock unit 18 are obtained as data relating to the measurement date and time (S6).

Then, the CPU 11 displays the acquired measurement data and data on the measurement date and time on the LCD of the display unit 19.
The measurement data and the data on the measurement date and time are displayed on the display panel 19 (S7).
This is stored in M14 (S8), and then the sequence control operation related to this measurement processing ends. Thus E
The measurement data stored in the EPROM 14 is displayed on the LCD display panel 1b together with the measurement date and time as data measured in the past in response to the operation of the push button 1c.

In S3, if the receiving unit 17 does not normally receive the signal radio wave (S3: NO), the CPU 1
1 repeatedly executes the determination processing of S3 until a signal radio wave is received. At this time, a message indicating that reception is not possible may be displayed on the LCD display panel 1b.

In S1, when the attached piece 2 is not inserted into the insertion portion 1d (S1: NO), the CPU 11 does not start the execution of the program related to the measurement process.
The determination processing of S1 is repeatedly executed. That is, in the case where the measurement of data and the display of data measured in the past are not performed, the driving power is not supplied to the LCD display panel 1c and the receiving unit 17, so that the required power consumption is always suppressed. In addition, the built-in battery can be used for a long time as low power consumption.

As is apparent from the above description, according to the data measuring device 1 having the above configuration and operation, the time is automatically adjusted based on the received signal radio waves, and the date and time after the automatic correction are measured. Since it is acquired as date and time, as long as the signal radio wave can be received normally, the measurement data can be obtained together with the accurate measurement date and time, and further, no troublesome operation for adjusting the time when the battery runs out etc. The handling operation at the time of measurement can be performed easily and easily without performing.

Although the date and time measured by the clock section 18 cannot be corrected depending on the reception state of the signal radio wave, the data measuring device 1 in the present embodiment is small and easy to carry. If the measurement is quickly performed by moving to a place where the situation is good, normal reception of signal radio waves becomes possible, and accurate measurement time can be obtained while correcting the date and time.

In this embodiment, a signal radio wave from a GPS satellite is received, and the date and time measured by the clock unit 18 are corrected. However, as another embodiment, a radio broadcast station or a television broadcast is used. The time may be corrected based on a time signal emitted from a ground station such as a station every predetermined time. In addition, if an existing system that emits signal radio waves with accurate time information is adopted, if a configuration that receives signal radio waves and acquires time data is adopted,
The data measuring device according to the present invention can be used by utilizing the existing system.

In the present embodiment, an example of a data measuring device for measuring a blood glucose level has been described. However, the present invention is not limited to a blood glucose level, and is not limited to a blood glucose level. May be used as the analyte. Broadly speaking, not only data on biological factors related to specimens in clinical tests,
The data measuring device according to the present invention can be applied to data measurement of an inorganic environment that varies depending on the measurement date and time.
